@reverse - A backslash seems to be misplaced in your expression. It should be '(?<v1>.+:\.+?\(.+?\).+)':

Try out the following as for regex101.com

(?<drive>\w)\:\\(?<first>[\w]+)\\(?<second>[\w]+)\\(?<third>[\w]+)\\(?<filename>[\d\w\.]+)

Try this out in splunk;

 | rex field=string "(?<drive>\w)\:\\\(?<first>[\w]+)\\\(?<second>[\w]+)\\\(?<third>[\w]+)\\\(?<filename>[\d\w\.]+)"

This will parse the entire path that you listed.

Do you want to extract DEF or do you want to extract the name of the second directory, where DEF is located?
